AI Technical Summary

Benefits of technology

The solution effectively reduces torsional vibrations and downtime by allowing precise control of the inertial moment of the drilling system, improving drilling efficiency and reducing equipment failure-related issues.

Problems solved by technology

In the field, especially in the offshore drilling field, downtime due to equipment failure is considered a major issue.
Whilst a drilling or other wellbore related operation involves the use of numerous pieces of equipment, studies seem to indicate that the top drive device is one of the major contributors to undesirable downtime.
A further relevant cause of loss of drilling efficiency and downtime due to equipment, e.g. drill bit, failure, is the occurrence of torsional vibration in the drilling tubulars string induced by stick-slip while rotary drilling.

Embodiment Construction

[0295]FIG. 1 shows a wellbore drilling installation with a trolley, top drive device, and rotatable head clamp and carrier according to the invention. It is envisaged that the depicted installation is part of an offshore drilling vessel for performing offshore drilling and / or other wellbore related activities, e.g. well intervention. It will be appreciated that, when desired, the invention is also applicable to land based drilling installations.

[0296]The installation comprises a drilling tower 1 that is here embodied as a mast with a closed contoured steel structure with at least one firing line 5 outside of the mast itself. For example the mast is arranged adjacent a moonpool of a drilling vessel, or over a larger moonpool with two firing lines along opposed outer faces of the mast 1 as is known in the art.

[0297]In an alternative design the drilling tower is embodied as a derrick with the firing line within the structure of derrick, e.g. the derrick having a lattice structure place...

Abstract

A method for drilling a wellbore, wherein use is made of a top drive device including: multiple electric top drive motors each having a rotor, a transmission to which the rotors of the multiple top drive motors are operatively connected, a rotary stem or quill operatively connected to the transmission allowing the rotary stem or quill to be driven by the top drive motors in order to impart rotary torque to a drilling tubulars string connected to the rotary stem or quill of the top drive device, wherein at least one, preferably each, of the top drive motors has an operable clutch device configured to selectively connect and disconnect upon command the rotor relative to the transmission. The method includes providing a command to the one or more top drive motors having a clutch so as to selectively connect and disconnect the rotor thereof relative to the transmission by operating the clutch.

Description

FIELD OF THE INVENTION[0001]The present invention relates to wellbore drilling with a top drive device.[0002]The present invention also relates to wellbore drilling using a wellbore drilling installation with a trolley and a top drive device, e.g. mounted on an offshore drilling vessel.[0003]The present invention also relates to the serviceability and to servicing of a top drive device of a wellbore drilling installation, e.g. mounted on an offshore drilling vessel.BACKGROUND OF THE INVENTION[0004]In WO2014 / 182160 an offshore vessel with a wellbore drilling installation is disclosed which comprises:[0005]drilling tower,[0006]a drill floor having a well center through which a drilling tubulars string can pass along a firing line,[0007]at least one vertical trolley rail supported by the drilling tower,[0008]a trolley, said trolley being guided along said at least one vertical trolley rail,[0009]a main hoisting device adapted to move the trolley with the top drive device up and down al...
